We’re looking for a Front-End Engineer who deeply cares about craft, usability, and building high-quality product experiences at scale.
You’ll work primarily with React, TypeScript, collaborating with designers and engineers to deliver clean, accessible, and reliable front-end interfaces across multiple core modules of our product.
You’ll have the opportunity to:
- Lead UI implementation for user-facing features used by some of Japan’s largest enterprise customers.
- Shape and evolve our Design System, component architecture, and front-end foundations.
- Improve performance, maintainability, accessibility, and visual consistency across the product.
- Collaborate with product and design from early exploration to final launch.
We value engineers who think about user experience, code quality, and long-term maintainability, not just getting tickets done.
Requirements
- 5+ years of professional front-end experience, with at least 2+ years in TypeScript.
- Strong understanding of component architecture, state management, and front-end performance.
- Experience working at a product-focused company.
- Ability to collaborate closely with designers and product managers.
- Strong sense of ownership over user-facing quality.
Nice to haves
While not specifically required, tell us if you have any of the following.
- Design Systems (tokens, components, theming)
- Automated testing for UI (Storybook, Vitest, Jest, React Testing Library, etc.)
- Accessibility (a11y best practices, semantic markup)
- Conversational-level Japanese (equivalent to JLPT N3)
